To"all-,whom it may concern:-

" Be it known that I, VVILL'IAM C. BASTIAN,

a citizen of the United States, residing at ew York, in th State of NewYork, have invented new and useful Improvements in Stems for Toba-ccoofwhich the following is a specificaon.

. Thel present invention relates to pipes.

, vIts object is to provide a pipe in which the condensed vapors andsalivawhich natural y collect in the stem,.will be prevented frompassing to the bowl, and which, together with the products ofdistillation from the tobacco, will, to a considerable degree, be

vIn order that the invention may be clear to those skilled in the art towhich it belongs, accompanying drawings a vpipe embodying my invention.vdrawings-Figure 1 is a view in lbntudinal section of a pipe made in ac-...enlarged view in longitudinal vzii por nce with my invention. Fig.2`is an section, of a part of the pipe stem. Fig. 3 is a view intransverse` section on line 3--3 of Fig. 2. Eig. 4 is a detail View inelevation, of the stem is probeing shown in dottedI lines.

the bowl 2 by a slip suitable mannerfis a bit, which is showny in. thepresent instance as made.v up of two parts, namely, the lpart l which isttedto the bowl-stem 3, and has an enlarged chamber or pocket 5 at itsupper end to which the smokefpassage 7 delivers, the upper end of saidsmoke-passage Joint, or in any V7, where it enters said chamber 5,Vbeing la'red as at-8 to the diameter of the chamber y so as to form avalve seat, presently to be described. The said bit member 4`is coupledto a mouth-piece 9 by a screw-thread or other suitable connection 10,the bit 4 being pref erably enlarged or swelled at the pointof union togive a proper landing or. gunction of the two separable parts. Said bitmouthpiece 9 is, of course, traversed by a smoke- Specification ofLetters Patent. Application med May 7, 1910. serial No. 560,051.

.member 13, and in passing through passage 11, as is customary, and, .asshown, the top wall of the pocket at the lower end ci the smoke-passage`11 at l the coupling end of the bit member 9 is flat, for a purposepresently to be described. It 'willbe seen that as thus constructed theytwo-piecek bit is provided between its ends with a chamber or pocket towhich the smoke passages to and from the bowl delivers, and throughwhich the smoke must pass.` In the said pocket 5 is placed a valvemember 13, Vwhich is of slightly less diameter than-the bore of thechamber 5, in. order that there maybe free passage between 4the valvemember 13 and thewall of the chamber'. The said valve member 13 has aconed end 14 by preference, and a liat top-face 15, and such coned endseats in the valve-seat formed by the flared section 8 atthe point ofunion of the chamber 5 and smoke passage 7, so as to norm-ally closesuch passage 7. The said valve mem ber 13 is preferably made of a lightabsorptive substance, such, for example, as meerschaum, and at a point-removed from its lower end is provided with one `or more transversepassages or which connect with one 17 extending to the upper end of thevalve member; the arrangement shown resulting in a cruciorm smokepassage with the vertical passage trapped at said valve member 13 isslightly shorter'than the chamber in which it is seated, so that it hasa slight play back and forth' in the chamber 5 to close and 'open apassage above the flared valve-seat Sat the upper end of smoke passage7.

When the pipe is in use, the said valve member 13, being 'of lightmaterial, will respond to suction on the bit, and lift, raising itscon'ed'end 14 from the seat 8 andallowing the smoke to come from thebowl 2 by stem 3 and bit member l to chamber 5 this lifting ofthe valvemember 13 at thesame time seating its upper dat end 15 against the innerflat wall 12 ofthe bit-member 9', so that smoke coming from Y to.chamber 5 can only pass to the passage 11 in bit-member 9 by traversingthe passages 16 and 17 in the valve member 13. The

4result of this is that the smoke, prior to reaching the mouth of thesmoker, must traverse passages in the absorbent valiget e Patented Jan.3, 1911.

.the '1 passage 7 its lower end. The

passages the hygroscopic character of the i material of which Said valvemember 1 3 1s -made will absorb and eliminate from the smoke the bulk ofthe liquid constituents held in suspension therein.

When suction ceases on the pipe the valve member 13 will drop to itsclosed position with its coned end 14 seated in the flared Sections fthe bahwmber 4., and this win eifectually close :the smoke-passage 7and.

preventany of the liquid of condensation which may have collected in thesmoke passages, orany saliva from the mouth of the smoker from passingto the bowl 2; but hold it. in chamber 5 and passage 17 to be absorbed'by the valve member 13.

It will be understood that the valve member 18` may be renewed from timeto time as it becomes saturated and foul, as these valve members may bejroduced at a slight thatthe disposition, size, and shape of thechamberthe valve-member, and in fact, all

of thel parts, may be varied; as this is a matter of fancy and designand in no `way a departure from my invention, which is not limited,except insofar as it is limited by the terms of the appended claims tothe details of the present i lustrative disclosure.

v I claim:

1.. A pipe having a chambered bit, and a valve in said chamber havingAsmoke-passages therein and normally 'closing the smoke-passage in saidbit.' y

2.y A pipe having a chambered stem, and a .valveiin said chamber 1navingtransverse and longitudinal smoke-passages therein and normally closingthe smoke-passage in said bit. i

3. A lpipe having a chambered bit, and a valve in said chamberhaving alongitudinal passage extending partially therethrough,

. and a transverse passage entering said longitudinal passage; saidvalve normally closing f the smoke-passage in said bit.

4. A pipe having a chambered bit, and a valve in said chamber'closed atone en d and having a smoke-passage therein which delivers at the otherend.y

5. A pipe havingy a chambered bit, and a valve closed at one end andhaving intertransverse and longitudinal smoke-passages which deliver atthe other end.

6. A pipe having a chambered bit', and a valve in said chamber having atrapped smoke-passage delivering at one end thereof.

7. A pipe having a chambered bit, and a valve in said chamber havin acruiform smoke-passage therein delivering at one end thereof. l

8. A pipe having a chambered bit, and a valve in said chamber having acruciform smoke-passage therein which is trapped at one end and deliversto the bit passage at the other end. l 9. A pipe having a chambered bit,avalve` in said chamber having a trapped longitu-f dinal passage and atransverse passage passx ing diametrically through said valve and in-.tersecting said longitudinal passage.

10. A pipe having a chambered bit provided with a coned valve-seat atits lower end, a coned valve seated therein and normally closing'thesmoke passage in said bit, a cruciform smoke-passage in said valvedelivering at the top thereof, said valve having` a flat top seatingsnugly about the smoke passage when the valve is raised so as t'oconfine the smoke to the bit passage.

11. A pipe having a chambered bit, a

valve in said chamber formed of absorbent' material and having atortuous .smoke passage therethrough,said valve havin a closed lower endwhich normally closes t e smoke passage in the bit and having an openupper..end which delivers to the smoke passage in the bit. L

'12. A pipe having a chambered bit, a valve of absorbent materialloosely fitting said chamber and having a, tortuous passage therein,said valve having a closed lower end which normally closes the smoke'passage in the bit,'and an open-upper end which delivers to the smokepassage in the bit.

13. A pi e having a chambered bit a, valve of ess length than the chamer' mounted therein and provided with a tortuous smoke passage therein,said valve having a closed lower end which normally closes the smokepassage in said bit, and an open upper end which delivers to thesmokepassage in the bit.

In testimony whereof I have hereiinit'oset my hand in presence of twosubscribing'` witnesses.
